Installed original fuel valve and connected to switching pushrod. Reviewed remaining fuel system components. Not sure that I'm going to reuse any of them. Only the Bendix fuel pump has regular fittings on it (NPT fittings in this case). All other components and lines have banjo fittings with what I'm assuming to be metric fittings. AN fittings and NPT fittings would not thread up to them. Whether I can source replacements for the metric banjo fittings or not will affect how authentic I'll want the plane to be.
Considering that the cause of the crash 40 years ago was because the fuel selector switch was put in the wrong position mid-flight, I might elect to remove it and simplify and modernize the entire fuel system. To be decided...
